A Home y Patented Jan. 30, 1934 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to agitating machines, and particularly to churns and the like for agitating and stirring fluids.

It is an object of my invention to provide a power device of this character of new and useful construction, having a superior simplicity and ruggedness, coupled with low cost of maintenance and operation.

It is also an important object of my invention 10 to provide a device of this kind which can be used with a variety of fluid or liquid receptacles whereby to operate upon liquids in their own containers without the necessity of providing a special container or receptacle in conjunction with and forming a part of the device of my invention.

Other objects and advantages of my invention will be apparent from a reading of the following description taken in connection with the drawing, wherein for purposes'of illustration I have shown a preferred embodiment of the invention.

In the drawing:-

Figure 1 is a general side elevational view of a prefered embodiment of the invention.

Figure 2 is a view taken from the right of Figure 1 looking in the direction of the arrows on the section line 2-2.

Figure 3 is a horizontal sectional view looking downwardly approximately on the line 3-3 of 39 Figure 1.

Referring in detail to the drawing the numeral 5 refers to a suitable base which may or may not be made a part of the device of my invention. The numeral 6 designates a suitable receptacle for containing the fluid or liquid to be agitated and stirred, the receptacle being replaceably located on one end portion of the base 5 for convenience, while the operative structure of the invention is located principally at the other end 0 of the base 5.

A body generally designated 7, which may be a single casting for economical reasons, comprises the casing portion 8 secured by means of lugs 9 to the base 5, an extension 10 from the back of the casing which joins with a standard 11 which rises above the casing and is provided with a longitudinally disposed vertical passage 12 for slidably and reciprocably receiving a square guide rod 13. The sides of the casing 8 are laterally expanded in a curvate manner as indicated at 13x whereby to accommodate interiorly a worm wheel 14 which is keyed upon a shaft 15 which is journaled horizontally through the casting '7 and 55, outward of the rear end portion is a counterweighted crank 16 to the outer end of which is connected at 17 a connecting rod or pitman 18 whose upper end is pivotally received upon a pin 19 carried at one end of a cross arm 20 carried at one end by the upper extremity of the slide or guide rod 13 as indicated at 21. A suitable 6o retaining means such as a cotter key 22 retains the pitman 18 on the pin 19.

Slidably and rockably associated with the outer end portion of the cross arm 20 is a vertically movable rod 23 having on its lower end a suitably formed agitator 24. It will be observed that the arm 23 and the agitator 24 are adapted to be adjusted as one vertically by means of the lock nut or thumb nut 25 extended through the arm 20. It will be obvious that the receptacle 6 is to be placed relative to the agitator according to its type and size and the level of the liquid or fluid therein, the rod 23 being adjustable for this purpose.

It will be obvious that as the shaft 15 is rotated 75 by suitable means, that the pitman 18 will be caused to reciprocate the agitator structure in an up and down motion.

Suitable means for driving the shaft 15 and the worm wheel 14 is provided in a suitable motor 26 which has its base 2'7 secured to the flat top 28 of the casing 8 by means of bolts 29.

Below the worm wheel 14 is transversely and horizontally journaled a worm shaft 30 carrying intermediate its ends the warm 31 in mesh with the worm wheel 14. Either end of the shaft 30 is provided with a drive pulley 32, 33. A belt 34 connects the drive pulley 35 of the motor with one of the pulleys 33, leaving the remaining pulley 32 free for driving other machinery. 0 I

A lubricating chamber 36 extends outwardly and at a slant from the portion of the casing 8 adjacent the end of the shaft 15 and the worm wheel 14, whereby the worm wheel and the worm 31 may be properly lubricated and inspected through the removal of the inspection plate 37 provided for closing the lubrication chamber 36.

Though I have shown and described herein a preferred embodiment of the invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in material and structure and arrangement of parts, consistent with the spirit of the invention and the scope of the subjoined claim.

What is claimed is:-

The herein described agitating means consisting essentially of a support having a lateral base extension and also having on said extension and fixed with respect thereto a vertical, hollo guide a dasher connected with and pendent from said cross arm, and a pitman movable in said space between the support and the standard and interposed between and connected to the said crank and the end of the cross arm remote from said dasher.
